Potential tuberculosis exposure at MacArthur High School in Irving ISD has prompted Dallas County Health & Human Services to recommend that all returning students in 10th, 11th, or 12th grade get tested for tuberculosis if they have not already been tested.
What We Know
Dallas County Health & Human Services is investigating possible tuberculosis exposure at MacArthur High School from the 2025-26 school year. The district is offering tuberculosis testing, but it is not required by DCHHS or the Texas Department of State Health Services.
Incoming freshman at MacArthur HS do not need to get tested. DCHHS says the risk to the public remains low, but recommends testing because inactive tuberculosis causes no visible symptoms.
